I render 2 triangles covering the whole surface using GLES20 context only. The problem is now that drawing just one single texture this way seems to be unreasonably slow. The framerate goes down from
Wh开发者_运维百科at are the exact differences between OpenGL ES 2.0 and OpenGL 4.1. I\'m aware of the fact that OpenGL ES 2.0 is a subset of OpenGL 4.1. But what exactly are the capabilities that are
I\'m trying to update my (little) knowledge of OpenGL ES 1.1 to 2.0 on the iPhone. The default OpenGL ES Application template for the iPhone draws a square and makes it translate up and down and works
How to i make the input handling run in a separate thread? I have modified the hello-gl2 example like this:
I am currently testing out all the features that a need in my game on the Android platform. I have only modified the hello-gl2 sample code, and added some textures, VBO\'s, FBO\'s and simple shaders i
I am making a program with opengl es 2.0 for android. I was planning on using VBO\'s to store my vertex data. But when I started to do so I noticed I am missing the function
I sometimes disable depth buffer writing via glDepthMask(GL_FALSE) during the rendering of a frame. That works perfectly fine on some GPUs (like the Motorola Droid\'s PowerVR), but on the HTC EVO with
I\'m writing a opengl es program (NDK) on andr开发者_开发技巧oid and I need render some particles.
Looking at the docs, I should be able to use BGRA for the internal format of a texture. I am supplying the texture with BGRA data (using GL_RGBA8_OES for glRenderbufferStorage as it seems BGRA there i
Is there a way to add callbacks in OpenGL ES similar to what DirectX has? I\'m trying to profile the GPU performance, so I\'m trying to figure out how long it took to execute certain parts of the GPU.
